first embodiment

[0015]Referring to FIGS. 1-4, a mask 10 for use in evaporation coating processes, includes a base board 100, a number of wing boards 200, and an aluminum foil 300. The wing boards 200 are detachably attached to the base board 100 and rotatable in a same plane 500 that is substantially coplanar with the base board 100. The aluminum foil 30 wraps around the base board 100 and the wing boards 200 along a contour 400 cooperatively defined by the base board 100 and the wing boards 200.

[0016]The mask 10 can be assembled by the steps S01-S05.

[0017]In step S01 the base board 100 and a number of wing boards 200, and the aluminum foil 300 are provided. The base board 100 is rectangular and includes a number of attachable portions 102 arranged in two parallel lines along the two long sides of the base board 100. The lengths of the wing boards 200 are variable, and each of the wing boards 200 has an attaching portion 202 at one end thereof.

[0018]In step S02, a selection is made concerning leng...

fourth embodiment

[0019]In step S03, a number of the attachable portions 102 are selected from all the attachable portions 102 depending on the coating requirements and the size and shape of the mask required. For example, in the embodiments of FIGS. 1-6, the number of the attachable portions 102 required to be utilized is fourteen. In FIG. 7, the number is six.

[0020]In step S04, the chosen wing boards 200 are detachably attached to the chosen attachable portions 102 by engagements between the attachable portions 102 and the attaching portions 202 such that the chosen wing boards 200 can be rotated in the plane 500. An arrangement or disposition of the chosen wing boards 200 can be set depending on the coating requirements and the size and shape of the mask required. For example, the same fourteen of the wing boards 200 can be attached to the base board 100 in the different configurations as shown in FIGS. 1-4 or FIG. 5. The chosen wing boards 200 can be rotated relative to the base board 100 to chan...

Abstract

A mask includes a base board, a number of wing boards, and aluminum foil. The wing boards are detachably attached to the base board in pairs, in a certain disposition and order and are rotatable relative to the base board in a substantially coplanar manner. The aluminum foil wraps around the base board and the wing boards so as to achieve a contour that is cooperatively defined by the base board and the wing boards.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to devices used in evaporation coating processes and, particularly, to a mask for use in an evaporation coating process.[0003]2. Description of Related Art[0004]In evaporation coating processes, workpieces near the source material may capture more evaporant than those far from the source material as evaporant near the source material will be thicker than that far from the source material. As a result, coating uniformity is not achieved. To solve the problem, a mask is employed to shield a part of the workpiece near the source material while not shielding more distant parts, to increase the coating uniformity. Such a mask may include a base wrapped with aluminum foil. The shape of the mask is fixed by the shape of the base, and cannot be changed when coating requirements are changed.[0005]Therefore, it is desired to provide a mask for use in evaporative coatings, which can overcome the above-mentioned problem.BRIE...
